Struct PublicKey 

pub struct PublicKey(/* private fields */);

A public key.

The key itself is stored as the CompressedEdwards y-coordinate of the public key. It is verified to decompress into a valid key when created.

Implementations

impl PublicKey

pub const LENGTH: usize = ed25519_dalek::PUBLIC_KEY_LENGTH

The length of an ed25519 PublicKey, in bytes.

pub fn as_bytes(&self) -> &[u8; 32]

Get this public key as a byte array.

pub fn from_bytes(bytes: &[u8; 32]) -> Result<PublicKey, KeyParsingError>

Construct a PublicKey from a slice of bytes.

Warning

This will return a SignatureError if the bytes passed into this method do not represent a valid ed25519_dalek curve point. Will never fail for bytes return from Self::as_bytes. See [VerifyingKey::from_bytes] for details.

pub fn verify( &self, message: &[u8], signature: &Signature, ) -> Result<(), SignatureError>

Verify a signature on a message with this public key.

Return

Returns Ok(()) if the signature is valid, and Err otherwise.

pub fn fmt_short(&self) -> impl Display + Copy + 'static

Convert to a hex string limited to the first 5 bytes for a friendly string representation of the key.

pub fn to_z32(&self) -> String

Encodes this key in z-base-32, the encoding used by pkarr domain names.

pub fn from_z32(s: &str) -> Result<PublicKey, KeyParsingError>

Parses a key from its z-base-32 encoding.
